| Abstract(E) | SCR system is effective post treatment device of diesel engine to remove NOx in exhaust gas. The purpose of this study is constructing simulation model capable of predicting spray behavior and NH3 concentration distribution. In order to achieve the purpose, it is necessary to clarify urea solution spray behavior injected by Urea SCR injector and concentration distribution of NH3 generated by chemical reaction in experimental analysis. In this report, NH3 generation process and the time required for the thermal decomposition of urea were estimated by measuring NH3 concentration at multiple measurement positions, and the reaction process of CFD were modified. |
